GRAIN-CAR DOOR.

T 0 all whom it may concern:

Be it known that we, GEORGE PAGET, CHARLES EDWARD PAGET, and ARTHUREDWARD PAGET, all of the town of Huntsville, in the district of Muskoka,in the Province of Ontario, Canada, have invented certain new and usefulImprovements in Grain-Car Doors, of which the following is thespecification.

Our invention relates to improvements in grain car doors, and the objectof the invention isfirst-to devise a means for fastening the door inposition at the sides, which will insure of no crevices being formedbetween the sides of the doors and the jambs due to the racking orjolting of the car secondlyto provide an improved means of holding thedoor in position without interfering with the ordinary jamb-thirdlytoprovide a simple means for locking the door from rising until it isreleased at the sides of the jambs-fourthly-to devise a simple means atthe bottom of the door for raising the door as soon as it has beenreleased at the sides-fifthlyto improve the operating mechanism forsecuring and releasing the sides of the door in relation to the jambsandsixthlyto devise an improved means of conveniently handling the door.To effect these objects we have constructed our door and the jambsthereof in the manner, which we shall presently describe.

Figure 1, is a perspective View of portion of a door showing the jambsand supplemental jambs with which it co-acts, so as to close the dooropening. Fig. 2, is a vertical section through the fastening devices atthe sides of the door. Fig. 3, is a view of portion of the side of thedoor showing it broken away. Fig. 4, is a sectional plan intermediatelybroken away. Fig. 5, is a perspective detail showing portion of thebottom bar of the door provided with a means for raising it. Fig. 6, isan alternative form of Fig. 5. Fig. 7 is a section on. line 77 of Fig.4.

In the drawings like letters of reference indicate corresponding partsin each figure. A A are the door jambs and B the sill.

C are the longitudinal boards of the grain door.

1) D are the end vertical battens, which are placed within the ends ofthe longitudinal boards C so as to leave projecting Specification ofLetters Patent.

edges C of the boards, which fit at the inside to the inside of the doorjamb.

C and C are the longitudinal upper and lower battens and D is thediagonal batten.

F are vertically grooved supplemental members secured to the door jambon the inside thereof. The groove has a curved portion F at the lowerend as shown in Fig. 7

E are the securing bars, which are provided with slots E through whichthe bolts E and E project. The slots E allow of lateral movement. Theheads of the bolts E are on the outside of the door and the fasteningnuts E on the inside. There are four bolts shown. The bolts E and E areprovided with enlarged portions forming shoulders 4 and 5. The portions5 being deeper than the portions 4 so as to extend through the plates Gand bars E.

r 6 are washers which encircle the bolts E and E and are located inrecesses formed in the battens D.

By means of the portions 4: and 5 and the washers 6 the heads of thebolts E are prevented from binding the plates G and bars E and also agood bearing surface is provided by the washers for the bars E to slideupon.

G are plates provided with diagonal slots through which the bottom boltsE and also the bolt next to the top bolt extends.

The bottom of the bar E is bent at E as indicated for the purpose ofallowing the bottom end of the bar E to slide inside of the bar H.

H is an angle bar secured as shown in Figs. 2 and 3 to the bottom of thedoor. In the front face of the bar H rectangular slots are punched. Thepunchings H thereof are turned baekwardly into a recess H formed in thebottom batten C of the door. In Fig. 6 we show an alternativeconstruction of this bar in which the punching of this slot is turnedoutwardly instead of inwardly into a recess.

I are reinforcing plates riveted on the securing bars E and extendingupwardly over the plates G and through-which the bolts E extend. Theouter ends of the plates E abut against the vertically grooved membersF, and the offsets E engaging with the curved portions F of the groovesin members F prevent the door being raised until the securing bars havebeen withdrawn volved in our invention we shall briefl describe theoperation and utility of the same.

The grain door is placed in position from the inside with the edge ofthe batten D against the inner side or edge of the groove member F. Theplates G are then moved downwardly and thereby throw the bars Eoutwardly into the grooves of the members F that is, in a position shownin Fig. 1 of the drawing. It will thus be seen that the door is securelyheld in position and the grain may be poured into the car and all theeffect will be to hold the projecting edges C of the door tight againstthe members F which practically form part of the door jamb therebyserving to aid in making the door grain tight. The securing bar E entersthe vertical groove of the member F also further aiding to make the doorgrain tight. The offset E on the plates E fitting in curved portion F ofthe groove in the member F serve to prevent the door rising from thesill when it is in its closed position.

In order to remove the door when the car is filled with grain all it isnecessary to do is to push the plates G upwardly so as to carry thesecuring plate E out of the groove of the member F and plate I away fromsuch members and then insert an ordinary lever into the holes formed inthe bar H and pry the door upwardly thereby allowing the grain todischarge underneath the bottom of the door into a suitable receptacle.When a larger quantity of grain has been discharged the door will fallback of itself on to the heap of grain remaining and will be entirelyfree.

Such a grain door as we have described will insure of no crevices beingformed between the edges of the door and the jambs owing to the rackingmovement of the car and allowing the grain to leak therethrough. Also adoor such as we have described may be easily and quickly locked in placeor removed when desired.

I What we claim as our invention is:

In a grain car door, the combination with the door, of a verticalgrooved member located in the door way at each end of the door havingoffsets formed in the groove and tongue members secured on the face ofthe door and slidable longitudinally of the door into the groove of thegrooved members and having offsets fitting the offsets of the groove, asand for the purpose specified.
